This reflective coating has high Reflectance (Ravg \u0026gt; 90%) over the 250 nm–600 nm wavelength range, making it highly suitable to collimate, focus, and image UV-band beams without introducing chromatic aberration. Metallic Coatings are easily oxidized, discolored, or peeled off in high-humidity environments. The SiO2 protective layer isolates the Metallic Coating from direct contact with air, preventing oxidation of the Metallic Coating from affecting optical performance. Currently, LBTEK's UV-enhanced aluminum-coated Concave Mirrors are available in three sizes (Ø12.7 mm\/Ø25.4 mm\/Ø50.8 mm) and seven different Focal Length (f) values (-25 mm to -500 mm). In addition to standard products, LBTEK also provides custom solution options for size, Focal Length (f), and wavelength range. If needed, please contact LBTEK technical support.\u003c\/p\u003e\n\u003ch3\u003eMetallic Coating Concave Mirror, UV-Enhanced Aluminum Coating: 250 nm-600 nm\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSubstrate material: Borofloat glass\u003c\/li\u003e\n\u003cli\u003eSilicon dioxide protective layer\u003c\/li\u003e\n\u003cli\u003eBeam focusing, collimation, collection, and image\u003c\/li\u003e\n\u003cli\u003eWavelength range: 250 nm-600 nm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe UV-enhanced aluminum-coated concave mirrors provided by LBTEK have high reflectance (Ravg \u0026gt; 90%) in the 250 nm–600 nm wavelength range, making them highly suitable for collimation, focusing, and imaging of ultraviolet beams without introducing chromatic aberration. These mirrors are available in three sizes (Ø12.7 mm \/ Ø25.4 mm \/ Ø50.8 mm) and seven different focal lengths (-25 mm to -500 mm), and can be paired with different mirror mounts based on size. Although the surface of metallic-coated concave mirrors is coated with a protective layer, it is still recommended to use and store them in a low-humidity, room-temperature environment. When handling mirrors, please wear protective products such as latex gloves or finger cots to prevent oils and other residues on fingers from contaminating the surface of optical components.\u003c\/p\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":67738676363418,"sku":"CM20-F50-UVAL","price":198.94,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/CM20-F50-UVAL-product.jpg?v=1791872534","url":"https:\/\/waveqvanta.com\/products\/metal-coated-concave-mirrors-uv-enhanced-aluminum-coating-250-nm-600-nm-cm20-f50-uval","provider":"WaveQuanta","version":"1.0","type":"link"}
